Abstract
Provided is a magnetism detection device by which it is possible to achieve a reduction in size and an increase in accuracy. A magnetism detection device includes: a magneto-impedance element; a magnetic field direction changing body; and a substrate that is formed of a semiconductor material and has an element arrangement recessed portion bottom surface and a back surface that face mutually opposite sides in a thickness direction, and a through-hole that reaches the element arrangement recessed portion bottom surface and the back surface and has a cross-sectional dimension that increases toward the main surface starting from the element arrangement recessed portion bottom surface. The magneto-impedance element is mounted on the element arrangement recessed portion bottom surface, and the magnetic field direction changing body is accommodated in the through-hole.
